The British war of Independence was fought between the freshly founded British Empire and the Elven Empire.
After a group of pro-democracy rebels (crazypirate1, Chailey, Bislo1, gildor_stinky and directoranivian) in the Elven Empire split off and founded the British Empire, the elven empire sought to act revenge and war was declared after the Elves refused to recognize the British Empire as a legitimate empire.
The war ended with British victory, after they unexpectedly gained huge support from many Elves and caused much unrest in the Elven Empire.
First British elections occurred soon after, and relations improved.
